Application filed September 26, 1927. Serial No. 221,966.

This invention relates to plumbing and has special reference to a plumbing plunger 5 simple and effective means for assembling the parts.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel de tails of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In th accompanying drawings like characters of reference indicate like parts :in the several views, and:

Figure 1 is a side elevation of a plunger constructed in accordance with this invention.

Figure 2 is a vertical section therethrough.

Figure 3 is a top plan view thereof.

In the construction of the devic here shown there is provided a cup 10 of rubber or the like and while this cup is here illusdated as of substantially hemispherical form it may be made of any shape desired. Extending radially from the center of this cup is a shank 11 having an opening 12 therein for the reception of a handle 13 which thus forms a continuation of the shank. Thus the shank is relatively rigid when compared with the cup 10. A compressor plate 14 is provided with openings in its center through which the shank extendsfthe in sertion of the handle serving to somewhat ex pand the shank and cause it to grip the compressor plate firmly. This compressor plate is of such shape that when the handle is pushed down the plate will engage the top of the cup and force down a considerable area of the central part of this cup. The exact shape of the plate may vary somewhat depending on the shape of the cup 10 but in the present instance the compressor is shown as a frusto-conical plate having an upturned peripheral flange 15 which formsa trough around the plate and is provided with perforations 16 in its. bottom. Thus the sharpedge ofthe plate is preventedfrom cutting into the rubber while at th same time any water that collects in the trough will drain therefrom. the drawings that the compressor plate is aboutthree quarters the diameter of th cup and while these proportions may vary it will be noted that a considerable area of the cup will be forced down whenthe handle is depressed. 'Ihe device is used in the ordinary way,

being placed over the outlet to the drain pipe in a basin, tub or sink andthe handle worked up and down.

There has thus been provided a simple It will be seen from and elficient'device of the kind described and for the purpose specified.

It is obvious that minor changes-may be made in the form and construction of the invention without departing from the ma terial spirit thereof. It is not, therefore, desiredto confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Havingthus described the invention, what 1s claimed as new, 1S2.

1. In a device of the kind described, a

flexible and elastic cup, a relatively rigid shank extending radially from said cup, a

r'rusto-conical compressor plate having'a central opening in which the shank tits and de pending from the shank over the central portion ofthe cup, an upturned flange on the lower edge of said plate, and a handle :torming a continuation of said shank:

2. In device of the kind described, a flexible and elastic cup, at relatively rigid shank extending radially from said cup, a frusto conical compressor plate having a central opening in which the shank fits and depending from the shank over the central portion of the cup, an upturned flange onthe lower edge of said plate, said flange forming a trough around theplate and having spaced perforations in the bottom thereof, and a handle forming a continuation of said shank. 3. In a device of the kind described, a flexible and elastic cup, at relatively rigid shank extending radially from said cup, 9. irusto-conical compressor plate having a; central opening in which "the shank fitsand depending from the shank over the central portion of the cup, an upturned flan e on the lower edge of said plate,jfsaid forming a trough "aI'Ohnd the" plate and hav- S ing spaced perforations in the bottom thereof, said shank having. a. recess extending inwardly from its end beyond the pointjof ange engagement of the plate on the shank, and ahandle having one end fitted in said recessto expand the shank and forcibly en- 10 gagethe shank and plate at the opening in the latter.

I Intestimony whereof I aflix my signature.
